My favorite part of cNs is actually the brownies. The brownies are amazing. Fudgy, gooey, topped with a few nuts. I'd go back for the brownies absolutely any day. Otherwise, it is a solid place to go and get a sandwich if you don't feel like making one. I had a BLT, and wish it had a little bit more lettuce. I plan on going again and trying something a little more adventurous next time.
The atmosphere was very earnest--I felt like I walked into the 70s or 80s. Wood panel walls, two picnic tables for seating inside, and shelves for storage make it seem like a very warm mom-and-pop place.
Parking, however, can be a bit of a nightmare. Either park behind the building (near Francis, Golden Rule and Stinkweed's parking lot) or prepare to fight for a spot in front of it.
